PLOW.

SPECIFICATION forming part of Letters Patent No. 262,716, dated August 15, 1882,

Application filed July 28, 1881,

- versible plows; and the objects of my improvements are, first, to provide a reversible plow that will turn a furrow uphill, so as to maintain the same depth of soil over those roots of a tree that extend downhill from its trunk as over those upon its upper side, in contradistinetion to the ordinary side-hill plow, which is incapable of turning a furrow except downhill, and of necessity piles the dirt against.

the tree upon its uphill side and plows it away from the lower side, leaving the tree upon the brink of a terrace, with its lower roots exposed and mutilated; second, to produce a reversible plow whose standard shall be vertical, while the landside shall be at right angles to the plane of the hill and its bottom or share parallel to the plane of the hill, while turning a furrow uphill, in contradistinction to the ordinary plow, whose bottom is at right angles to the standard, necessitating an inclined position of the standard while turning afurrow uphill; third, to provide a reversible plow whose landside shall have the proper divergence from the line of the beam to secure the desired width of furrow without adjusting the clevis; fourth, to produce a reversible plow having a right-hand and left-' hand mold-board that may be used interchangeably upon the same share or point, (which iseommon to both,) or, when desired, with one mold-board only, thus forming a simple right or left hand plow, capable of being used as such without being incumbered by the weight of the other mold-board, together with its standard, landside, and share, as is the case with former existing reversible plows having a right and left hand mold-board in connection with two shares pointing in opposite directions, and two landsides, being simply two plows placed baek to back. I attain these objects by mechanism illustrated in the accompanying drawings, in which-- Figure 1 is a rear view, showing the left-hand (No model.)

mold-board in position, the standard vertical, and the rear end of share raised above the level of the bottom of the landside. Fig. 2 shows a side view of the standard, handlebrace, and landside, with share and moldboard removed. Fig. 3 is a top view of landside and standard in position for the righthand mold-board. The dotted lines show it reversed for the left'hand mold-board. This view also shows the device by which land is secured. Fig. 4 is a front view of the plow with itsleft-hand mold-board in position, showing by dotted lines the position of the righthand mold-board when the left-hand moldboard is removed and the share oscillated to the right for that purpose. Figs. 5 and 6 are representations of the backs of the left-hand and right-hand mold-boards with lugs a a.

Similar letters referto similar parts throughout the several views. The standard S, Fig. 2, may be made of wrought, malleable, or cast iron, or steel, (preferably steel) and provided with the short journalsJ J atits lower frontandrearextremities. The landside l 8 may be made of cast-iron, sheet-steel, or cast cast-steel, (preferably the latter,) with one face at about right angles to the other, (so that while one face serves as a landside the other acts as a bottom, and vice versa,) and sufficiently wide at the frontend to completely shield the frog f and necessary bolts from contact with the bottom of the furrow and from contact with the land, thus avoiding, especially in adobe or adhesive soils, the lifting out of the plow caused by such soils accumulating and being impacted upon the exposed bolts, nuts', brace, frog, and unfinished or unpolished bottom surfaces of ordinary plows.

The standard S and angle-landside l s are attached together by the front and rear frogs, f and F, (see Fig. 1) which are fastened to the landside by plow-bolts, and are connected to the standard by holes fitting thejournals J J, Fig.2. This pivot-point at J Jpermits either angle of the landside to be brought into position-e. 9., to the right of the standard for a left-hand plow or to theleft of the standard for a right-hand plow.

The share 1? P is placed in position and firmly attached to the landside by means of a slight socket upon its lower surface, nearits point, fitting over the pointed front extremity of tlie landside, and is further secured in position by means of two plow-bolts connecting its'rear end to the arms 0 O of the front'frog,f. This front frog,f should be made of malleable iron or struck up out of sheet-steel in a drop provided with proper dies; audits arms 0 G extend back and upward in such a position as to come just under the shin of the mold-board,

their rear ends being turned in ward in position to extend through the standard, (by means of a holenear its front edge,) presenting the notch 00 upon the opposite side of the standard. The rear'frog, F, may be made of sheet-steel or malleable-iron, with hole for journal J, and flanges whereby to bolt it to the angles of the landside.

The mold boards, Figs. 5 and 6, may be made of any desirable material adapted to the locality in which they are to be used, and in the. forms most approved for the special service required of them--e.g.,of a bold or somewhat abrupt anglefor loose loam or a longer sharper angle for sod and heavysoils; or, if desirable, two or more forms of mold-board may be fitted to the same plow.

The mold-boards are provided with the lugs to a. a a upon their lower side at the front end and in such position as topass through the arms 0 0, thus forming a most simple and efiective connection between the mold-board and the share. The mold-boards must further be provided. with the short arm or pawl 1", which assumes abearing in the notch 00, and, being held down firmly in the notch by the hook-brace 0, rigidly locks the several parts in position, when it is ready for service.

To reverse the plowthe hook-brace 0 is detached, when the mold-board is readily lifted out of its position. This allows the share and landside to be (see dotted lines, Figs. 3 and 4) reversed or oscillated upon the journals J J until the other arm 0 comes in contact with the standard projecting through it and presenting the necessary bearings for the moldboard, which is readily dropped into position, and the several parts are firmly locked together by the hook-brace 0, thus attaining the fourth object of my invention.

The third object is attained by means of placing the hole in the rear frog, F, (for journal J,) close to the landside, while the bearing in the front frog,f, (forthe journal J,) is at a greater distance from the landside, thus causing the line of the landside to diverge from the line of the beam, as shown by Fig. 3.

The second object is attained by the arms G 0 coming in contact with the side ofthestandard S when the share (while being oscillated or reversed) arrives at the exact position desired, retaining it in this position, with its bottom forming an acute angle to the vertical of the standard. (See Fig. 1.)

I am aware that prior to my invention reversible plows have been made by connecting together a right and a left hand plow back to back, having two shares pointing in opposite directions at the extremities of a landside of double the length required for one plow, each plow having a standard, the tops of which were connected by a cap-piece and pivoted to a beam by means of a bolt, the two plows being undetachable from each other, thus encumbering the team and plowman with more than double the weight and the manufacturer with double the expense for material required in this my present invention. I.theret'ore do not claim a reversible plow with two moldboards, broadly; but v WVhat I do claim as my invention, and desire to secure by Letters Patent, is-

1. The combination, in a reversible plow, of the share or point P, adapted to receive either mold-board right or left, the pivoted landside ls, the notched arms 0 (J, and standard S, substantially as described.

2. The combination, in a reversible plow, of the angular landside l s,journals J J, frogs f and F, and standard S, substantially as described.

3. The combination, in a reversible plow, of the point P, adapted to receive the lugs 11 a, and arms 0 0, having notches a: m to engage with the lugs 1", substantially as and for the purpose specified.
